Title: High-frequency heating device
Inventor: TANAKA TERUYA
IPC: H02M7/538
Filed: 1988-08-26
Abstract: PURPOSE:To reduce the power loss when a switching device is turned off by providing a device removing charges between the gate and emitter of a bipolar type MOSFET and a device suppressing the oscillation of the gate voltage. CONSTITUTION:The switching circuit 13 of an inverter circuit 3 is connected to a driving circuit 15 via a parallel circuit of a resistor R10 and a capacitor C10. When the circuit 13 is turned off, charges between the gate and emitter of an FET101 are instantaneously charged, i.e., the capacitor C10 removes the charges between the gate and emitter. Since the parallel circuit of the resistor R10 and the capacitor C10 is inserted between the gate of the circuit 13 and the circuit 15, the gate voltage VGE when the circuit 13 is turned off is lowered to 0V, the circuit 13 is surely and instantaneously turned off, thus the ringing generated by the inductance existing in a wiring material between the circuit 3 and the circuit 15 can be suppressed.

Title: Ink jet head and manufacture thereof
Inventor: WATANABE KENJI
IPC: B41J2/16
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent an ink jet head from being clogged with ink by subjecting the ink touching part to hydrophilic treatment thereby keeping fluidity of ink in the ink jet head. SOLUTION: An ink jet head provided with an ink channel 3 having an ink touching part is placed in a reaction container which is then evacuated. It is then treated for a specified time by introducing gas containing fluorine at a specified concentration under a specified pressured. Subsequently, nitrogen is substituted for the gas in the reaction container and the ink jet head is taken out before the ink channel 3 part is subjected to hydrophilic treatment. Consequently, fluidity of ink can be kept in the ink jet head and the ink jet head can be prevented from being clogged with ink.

Filed: 1986-09-11
Abstract: PURPOSE:To entirely eliminate the stray light in a housing and to improve the detection sensitivity of reflected light by providing a light absorptive layer in such a position where the light passing the lens part is not shielded to prevent the incidence of the stray light generated in the transparent housing, the top surface of which is formed as the lens part, to a light receiving part. CONSTITUTION:The light released from a light emitting diode 3 is focused in the lens part 1A and is projected to; for example, the recording surface of an optical disk, etc. The reflected light thereof is entered through the lens part 1A to two pieces of light receiving elements 4A, 4B. The electric signals outputted from the respective elements 4A, 4B change according to the inclination of the optical disk; therefore, the inclination of the disk is detectable. Even if the light Ps released from the diode 3 is projected to the side of the housing 1, the light is absorbed by the light absorptive layer 6 which is dyed black. The incidence of such light as the stray light to the element 4A or 4B as shown by alternate long and short dash line is obviated.

Abstract: PURPOSE: To prevent a drop of a low pressure side pressure due to an insufficient refrigerant circulating amount at the time of a low load operation by connecting a control low pressure switch to a bypass solenoid valve of a bypass pipe for supplying a refrigerant by detouring a condensing pressure regulating valve by a wiring. CONSTITUTION: The air-cooled type air conditioner comprises a control low pressure switch 23 provided at a pipe 22 for connecting an evaporator 4 of a low pressure side pipe to a compressor 1, a bypass solenoid valve 18 electrically connected to the switch 23. In the case of a low load operation, a solenoid valve 6 of a bypass route 10 is opened via a high pressure switch 11 to conduct a bypass operation. When an operation is continued for a long time so that circulating refrigerant is stored in an air cooled condenser 7 and a refrigerant pipe 8 with the result that an absolute amount of the refrigerant is insufficient and the pressure is lowered, the switch 23 is operated to open the valve 18. Then, part of the stored refrigerant is circulated via the condenser 7 and the pipe 8 to be supplemented to raise the low pressure side pressure to a normal refrigerating cycle.  Accordingly, a drop of the low pressure side pressure due to insufficient refrigerant circulating amount at the time of the low load operation can be prevented.

Title: Evaporating device for volatile substance
Inventor: MORIZAKI MOTOJI
IPC: H01L21/205
Filed: 1985-09-26
Abstract: PURPOSE:To prevent the volatile substance from pushing out to a gas flow-in tube by a method wherein a pressure regulator is provided when the pressure of gas is a gas exhaust pipe is higher than the pressure of gas in a gas flow-in pipe, and the difference of both pressure is zeroed. CONSTITUTION:A gas flow-in pipe 1 and a gas exhaust pipe 5 are connected directly with a bypass pipe 6. Also, when the gas pressure of the gas exhaust pipe 5 becomes higher than the gas pressure of the gas flow-in pipe 1, a pressure regulator 7 with which gas is flowed from the side of the gas exhaust pipe 5 to the side of gas flow-in pipe 1, is connected in the midway of the bypass pipe 6 through the bypass pipe 6. The pressure regulator is constructed in such a manner that when the pressure on the B-side (the side of gas exhaust pipe 5) became higher than the pressure on the A-side (the side of gas flow-in pipe 1), a spring 31 is extended to the A-side, a gap 32 is generated, and gas flows to the A-side from the B-side in accordance with the difference of the gas pressure. When the pressure of the A and B sides becomes same, the spring 31 returns to its original position, and the gap 32 is closed. When the gas pressure of both sides becomes same, the pushing out of the volatile substance into the gas flow-in pipe 1 can be prevented.
